Question 1

Are new windows more likely to crack?

Accepted Answer

Stress cracks can sometimes appear in newly installed windows, but they are not necessarily related to the age or quality of the window itself. According to Pella engineers, stress cracks are often influenced as much by the architectural design and shading conditions of the home as by the glass in the window. Changes in sunlight exposure, temperature fluctuations and shading patterns can all contribute to thermal stress on the glass over time.

Question 2

How do I identify a thermal stress crack?

Accepted Answer

Thermal stress cracks are often identifiable because they begin at the edge of the glass and extend inward at a perpendicular angle. According to Pella customer support representative Faye Howard, the crack will typically run straight from the glass edge for about a half-inch before it may begin to spider in other directions. In some cases, cladding or trim may make the edge of the glass difficult to see.

Question 3

Can a stress crack in a window be repaired?

Accepted Answer

In some cases, a stress crack may be temporarily repaired using a glass repair solution designed to help limit the spread of the crack. However, because stress cracks are caused by ongoing expansion and contraction in the glass, the crack may continue to grow over time. Depending on the size, location and severity of the damage, replacing the glass or the entire window may be the best long-term solution.

Question 4

What are the three types of window cracks?

Accepted Answer

Pella engineers recognize three general types of window cracks: thermal stress cracks, impact cracks and pressure cracks. Thermal stress cracks typically begin at the edge of the glass and form at a perpendicular angle due to sudden temperature swings or shading changes. Impact cracks create a starburst pattern that radiates outward from a central point after the glass is struck. Pressure cracks resemble the curve of an hourglass and can occur in insulating glass windows when there are significant elevation differences or drastic pressure changes in the weather.

Question 5

Why did my window crack on its own?

Accepted Answer

Windows that crack without an obvious impact are often experiencing thermal stress cracks. These cracks develop when different areas of the glass heat up or cool down at uneven rates, causing the glass to expand and contract unevenly. This most commonly occurs when one portion of the window is exposed to direct sunlight while another remains shaded. Rapid seasonal temperature swings, large panes of glass and partial shading from trees or roof overhangs are some of the most common causes.

Question 6

Is vinyl always the cheapest window material?

Accepted Answer

Vinyl is often considered a value-focused option because it typically offers an accessible starting price point and low maintenance requirements. However, project costs can vary based on window size, style, glass packages and installation complexity.

Question 7

Does upgrading window material increase home value?

Accepted Answer

Window replacement projects can contribute positively to resale value, particularly when they improve energy efficiency, curb appeal and overall home condition. According to the Remodeling 2020 Cost vs. Value Report, new vinyl windows can return homeowners more than 73% of the project cost at resale.*

Beyond material selection alone, buyers often respond to the overall condition and performance of the windows. If a home’s windows appear near the end of their lifespan, it may influence perceived value during a sale. Upgrading window materials can play a role in strengthening that perception, especially when the improvement aligns with the home’s architecture and the expectations of buyers in your market.

Question 8

Which window material lasts the longest?

Accepted Answer

Longevity varies based on climate, installation quality and maintenance. Each material is designed to perform well when properly specified and cared for.

Question 9

Is fiberglass worth the extra cost?

Accepted Answer

Fiberglass often appeals to homeowners seeking added durability and dimensional stability, particularly in climates with wide temperature swings. Whether it’s worth the cost depends on performance priorities and long-term expectations.

Question 10

Why is wood more expensive than vinyl?

Accepted Answer

Wood typically involves higher material costs and greater customization, which increases manufacturing and finishing requirements compared to vinyl.

Question 11

What adds the most to window replacement cost?

Accepted Answer

While every home is unique, the most significant drivers of project cost typically include the choice of premium frame materials, the complexity of a full-frame installation compared to an insert and the selection of specialized glass or custom-shaped units. Additionally, addressing unforeseen structural issues, such as frame rot or water damage discovered during the removal process, can also influence the final investment.

Question 12

Does my home’s age affect replacement cost?

Accepted Answer

It can. Older homes may require more detailed labor to handle delicate trim or to address hidden issues like frame rot that only become visible during the replacement process.

Question 13

Does replacing more windows reduce cost per window?

Accepted Answer

Generally, yes. Larger projects allow for better labor efficiency and streamlined logistics, which may make the project more cost-effective on a per-unit basis.

Question 14

Why do two window quotes differ so much?

Accepted Answer

Quotes vary because they reflect different choices in glass, installation methods, and the thoroughness of the work required to protect your home’s structure.

Question 15

Can I replace windows in phases?

Accepted Answer

Yes. Phasing a project is a common way to manage budget flexibility while still addressing your home's most immediate needs.

Question 16

Why does replacing many windows cost more than the sum of the parts?

Accepted Answer

Beyond the products, replacement projects can involve complex installation requirements, regional labor rates, and the specific condition of your home's exterior and interior.

Question 17

How long do replacement windows last?

Accepted Answer

Lifespan varies by material, installation quality and environmental exposure. Proper installation plays a key role in long-term performance.

Question 18

Are cheaper windows worth it?

Accepted Answer

Lower-cost options may suit some projects, but durability, comfort and maintenance should be considered alongside upfront price.

Question 19

Does full-frame replacement cost more?

Accepted Answer

Yes. Full-frame replacement generally costs more due to additional labor and materials.

Question 20

Is it cheaper to replace all windows at once?

Accepted Answer

Replacing multiple windows together can streamline installation, but total cost still depends on window size, type and configuration.

Question 21

Why do window quotes vary so much?

Accepted Answer

Quotes reflect differences in materials, window sizes, installation methods, regional labor rates and project complexity.

Question 22

When to install windows?

Accepted Answer

Windows can be installed any time during the year, including winter. Spring is the busy season, but window installation is not necessarily a seasonal project. If your windows need replaced, there’s no need to wait for warmer weather. Pella professionals install one window at a time and take extra precautions to ensure your home stays warm and comfortable during winter installs.

Question 23

How long does it take to install windows?

Accepted Answer

Depending on the type of installation (pocket replacement or full-frame replacement), it can take anywhere from a few hours to two days for a professional to install a window. This estimate assumes that the conditions of the project are ideal and no unexpected issues arise. It usually takes longer for homeowners who choose to install windows themselves.

Question 24

How much do replacement windows cost?

A number of factors affect the price of a window, including window type, material, features and options such as grilles and hardware and more. To get accurate pricing for your unique project, schedule an in-home appointment with a local Pella expert.

Question 25

How are replacement windows installed?

Accepted Answer

There are two types of methods for installing replacement windows. The complexity of your window renovation project will determine which method is right for you.

If you’re doing a more complex upgrade to your existing windows, you’ll have to look into full-frame installation. As far as who does the installation? You can work directly with one of our distributor installers who are versed in all things Pella windows or look into hiring an independent contractor locally.

Should I replace my windows all at once?

Accepted Answer

It depends on why you are replacing windows. If a window is not functioning properly or is broken, it might be best to replace only that window.
